Definitions

  • the improvements which are the subject of the present invention apply more particularly, although not exclusively, to a mechanism for controlling the claw frames of a crowd forming device for a ribbon loom.
  • a crowd formation device must have the smallest possible overall dimensions so as to reduce the overall overall dimensions and the masses in motion.
  • the control mechanism comprises on each side of its frame, on the one hand, a first lever articulated to this frame by one of its ends and to one of the claw frames by its end. opposite, while said lever is associated with a reciprocating control and on the other hand a second lever whose ends are articulated respectively to said claw frame and to the frame so that the latter, the two levers and the frame constitute a deformable parallelogram .
  • the distance separating the axes of articulation of the two levers to the frame can be greater than the spacing between their axes of articulation to the frame in order to communicate to the latter a movement such that in the high position it is oriented obliquely relative to at its low position.
  • the appended drawing given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • the single figure of the drawing illustrates in elevation a device for forming the crowd of a weaving loom, comprising a mechanism for controlling the claw frames established according to the invention.
  • a device for forming the crowd of a loom made in the form of a weaving mechanism of the Jacquard type comprising a frame 1 inside which move two claw frames 2 only one of which has been shown to simplify the drawing.
  • Each of the claw frames comprises a multiplicity of knives, not shown, intended to cooperate with associated hooks to the beams which control the various arches. Since such a crowd training device is well known in practice, it is not worth describing it in more detail.
  • each of the claw frames is arranged on either side of the frame 1, so that said claw frames are in cantilever with respect to their mechanism ordered.
  • This arrangement is made possible by the fact that the width of the frame 1 is small when dealing with mechanics intended for the manufacture of narrow ribbons on a loom.
  • the frame 1 is crossed by a control shaft 3 rotating in synchronism with that of the trade control.
  • This shaft protrudes on each side of the frame to carry an eccentric 4.
  • Each eccentric constitutes a crank pin around which is rotatably mounted the head of a connecting rod 5 whose foot is articulated on an axis 6 integral with the top of a lever 7 of general triangular shape.
  • One of the ends of the lever 7 is articulated relative to the frame 1 around an axis 8, while its opposite end is articulated to the frame 2 by means of an axis 9.
  • the frame 2 is still connected to the frame by a second lever 10 whose hinge axis 11 on this lever is at a distance d below the hinge axis 9 of the lever 7 and which is different from that D separating the axis 8 from the axis 12 of pivoting of the lever 10 relative to the frame 1.
  • the assembly of the two levers 7 and 10 therefore constitutes an irregular deformable parallelogram.
  • the connecting rod 5 causes the lever 7 to pivot about the axis 8. Due to the presence of the lever 10, the frame 2 therefore moves so that in the high position, illustrated in solid lines, it is oriented obliquely to its low position shown in broken lines.
  • eccentric 4 which controls the frame 2 is offset 180 ° relative to that which controls the second frame, not shown, so that these two members move alternately in opposite directions in the known manner.
